This invention relates to improvements in the manufacture of billiard tables and pool-tables and more particularly to the construction of the bed or playing plate.

Billiard tables and similar appliances are already known in which the playing surface, plate or bed, upon which the game is executed, is made of metal, as for instance cast-iron, steel, light metal or metal alloy and of course afterwards covered with cloth in the usual manner; the metal plate being provided with reinforcing ribs and consists of one piece or of a plurality of pieces. However it has been found that a self-supporting solid metal plate must be of considerable thick- 5 ness for imparting it with the characteristics re.-

quired for playing. In view of the weight, the thickness of the metal plate must be kept within reasonable limits, as otherwise difficulties arise in connection with the conveyance and erection of the billiard table.

The above-mentioned drawbacks are obviated according to the present invention by the combination of the metal construction with a playing plate of a self-supporting single piece of moulded artificial stone, such as concrete, re-

inforced concrete, terra-cotta, xylolit and so forth, whereby the weight of the bed or playing-plate is reduced although the same is of the necessary thickness. Playing-plates composed of a number of parts of reinforced concrete are already known. However the known playing-plates of this kind are intended as substitutes for marble, slateor other plates of natural stones and they are not self-supporting, but must be placed on a special supporting skeleton particularly on the usual wooden frame, so that the construction of the billiard table is not rendered more simple.

The principal feature of the present invention consists in the combination of the said self-supporting plate of moulded artificial stone with means moulded or cast in said plate for securing the cushion support and if desired also the legs.

Two modes of carrying out the present invention are illustrated by way of example on the accompanying sheet of drawing in which Fig. 1 is a vertical longitudinal section through a billiard table without legs. Fig. 2 is a similar view of a modified construction of billiard table. Figs.

3 and 4 are plan views of a part of the playing-plate or bed.

In the constructions according to Figs. 1 and 2, the playing-plate or bed I consists of a combination of metal and a material such as artificial stone capable of being casted or moulded, for instance concrete, reinforced concrete, terracotta, xylolit and so forth.

In the construction shown in Fig. 1, the playing-plate I is moulded in a metal frame 2 and l a steel support 4 is screwed to the latter by means of screws 3. The frame. 6, carrying the cushioning means, is secured to the support by means of screws 5. Further a wooden frame I is fixed to the steel frame 2 and serves for securing the cloth. The structure just described is enclosed by an outer frame 9. r

In the construction shown in Fig. 2, nuts 9 are moulded or cast in the playing plate I for securing the frame 8 carrying the cushioning means. This frame 8 is secured to the playing plate I by means of headed screws Ill, which are screwed into the nuts 9 and bear on a ledge II, holding down the frame 8. The heads of, the screws ID are hidden by wooden covers I2. As shown in Fig. 4, the nuts 9 may be formed in long metal bars by providing the same with screw-threads spaced apart at suitable distances. However also separate nuts 9 may be provided, which individually are moulded or cast in the playing plate I. L

Screws I3 are moulded or cast in the playing plate, which serve for the attachment of the legs of the billiard table. The means I3 for securingthe legs may consist of brackets, which are moulded or cast in the playing plate I and the screw-threaded ends of which project from the underside of the latter.

I wish it to be understood that I do not limit myself to the particular constructional form shown in the drawing merely by way of example, various departures being possible especially in the details, without constituting, however, departures from the invention.

What I claim is 1. A billiard table, pool table and the like, comprising in combination a self-supporting playing plate of a single piece of artificial stone, means cast in and extending out of said plate for, securing legs directly to said plate, and means in said plate for attaching the cushions to said plate.

2. A billiard table, pool table and the like, comprising in combination a self-supporting playing plate of a single piece of artificial stone, metal brackets cast in said plate and provided with screw-threaded ends extending out of said plate for securing legs directly to said plate, and means in said plate for attaching the cushions to said plate.

3. A billiard table, pool table and the like, comprising in combination a self-supporting playing plate of a single piece of artificial stone, means cast in and extending out of said plate for securing legs directly to said plate, a support carrying the cushion means mounted on said plate, screws disposed vertically with respect to the plane of said plate, and means located in said plate and engaged by said screws for forcing said support on to said plate.

4. A billiard table, pool table and the like, comprising in combination a self-supporting playing plate of a single piece of artificial stone, metal brackets cast in said plate and provided with screw-threaded ends extending out of said plate for securing legs directly to said plate, a support carrying the cushion means mounted on said plate, screws disposed vertically with respect to the plane of said plate, and meanslocated in said plate and engaged by said screws for forcing said support on to said plate.

5. A billiard table, pool table and the like, comprising in combination a self-supporting playing plate of a single piece of artificial stone, means cast in and extending out of said plate for securing legs directly to said plate, a support carrying the cushion means mounted on said plate, screws disposed vertically with respect to the plane of said plate, and means located in said plate and engaged by said screws for forcing said support on to said plate, and a metal bar provided with screw-threaded holes cast in said plate for 5 co-operation with said screws.
